This thesis studies segmentation and categorization of highway road data, with the ambition that the understanding gained could be used for virtual verification of road scenarios for self-driving systems. We will look at a few approaches for segmentation of the road data, such as heuristics as well as methods involving optimization. The result of the segmentation is categorized and we then explore

The world is currently facing many great challenges, including a rising inequality as a result of the benefits occurring from economic development accrues to some individuals on the expense of others. This is an issue which is even more significant in the Global South. Hence, social innovations have been proposed as an important factor to tackle this problem. Yet, many social innovations fail not

This master thesis was produced with the intention of being a conceptual study of existing solutions and development of new solutions for a train mounted system for collection of brake dust particles from trains. Furthermore, an investigation of the risks attributable to brake dust and why the reduction of it is necessary was made. The problem was approached systematically through the adoption of

The current global scenario is such where impact on the environment is becoming a rising concern. Global automotive manufacturers have focused more towards hybrid and electric vehicles as both more aware customers and governmental legislation have begun demanding higher emission standards. One of the many ways that Volvo Car Group approaches this trend is by mild hybridization which is by assistin

Many regions around the world suffer from occasional or permanent droughts. Recent years have shown that although Sweden is not a water scarce country, it is vulnerable to dry peri- ods. As drinking water is applied in not only households, but within agriculture and indus- tries, this thesis explores the opportunities to achieve an improved management of water re- sources, by investigating the pos

The present study aimed at investigating the recent phenomenon termed Fear of missing out (FOMO), which builds on a feeling of constantly having to be connected to what other people are doing on social media in order to not miss out. The purpose of this study was to see if a link between FOMO and social media addiction is present and if Swedish university students’ well-being and academic performa

A prototype invasive (quasi-parasitic) thermal-neutron beam monitor based on isotropic neutron scattering from a thin natural Vanadium foil and standard $^3$He proportional counters has been conceptualized, designed, simulated, calibrated, and commissioned. As the beam monitor is invasive, very low neutron-beam attenuation is a necessary characteristic. Further, response linearity over as wide a r

The development of today’s energy-efficient dwellings often results in highly technical building solutions. We try to shield ourselves and our buildings as much as we can from the outdoors and subsequently loose an essential connection to the elements. Traditional design principals fall into oblivion and high-rise glass towers are justified with technological progress. By implementing selective st

Miljonprogrammet pågick mellan cirka år 1965 till år 1975 och hade som mål att producera en miljon bostäder för att tackla de bostadsproblem som rådde i Sverige under 1950-talet. Med ett stort fokus på att producera så många bostäder som möjligt föll valet till en början på att främst producera flerbostadshus. Byggnaderna från miljonprogrammet börjar närma sig en ålder av 50 år vilket vanligtvis i

Denna studie har syftat till att undersöka hur negativa och positiva emotioner, likväl som rädsla och mod, spelar roll i “the knowing-doing gap”och påverkar utövandet av ledarskap hos chefer i svenska organisationer. Undersökningen var en kvalitativ studie baserad på semistrukturerade intervjuer med tematisk analys, som undersökte hur sju chefer upplever att deras ledarskap påverkas av emotioner.

Additiv tillverkning, eller 3D-printing, är på grund av sina många fördelar en ständigt ökande tillverkningsmetod. Designfriheten, det reducerade materialspillet, förkortad tid från ritning till färdig produkt och förmågan att kunna printa rörliga delar gör 3D-printing intressant för många olika användningsområden. Ett användningsområde där relativt lite forskning gjorts men som har ett ökat intreAdditive manufacturing, or 3D-printing, is due to its many advantages an increasingly used form of manufacturing. The design freedom, reduced material waste, shortened process from drawing to finished product, and the ability to print moving parts make it extremely interesting for many applications. One application where not much research has been done, but there is an increasing interest, is the

WHO The World Health Organisation (WHO) recognises that demographic trends play an essential role in the overall development of a country and improvements in economic, social and health conditions. One of the grand theories of population studies is the Demographic Transition Theory, a linear and universal model of population change. The greatest challenge to the Demographic Transition Theory’s des

This bachelor thesis in social anthropology researches the subject of integration and refugee narratives in contemporary Danish society. It is firstly a study of what integration means in Danish culture and how integration is debated in the Danish public debate. Secondly it is a study of how the Danish public discourse reflects itself in the refugee narratives. Moreover, this thesis investigates t

Radar har använts sedan 1940-talet för att mäta och övervaka nederbörd. Under de senaste åren har X-bandradarn visat sig vara ett verktyg som kan förbättra indata till avrinningsmodellering inom urbana avrinningsområden. Detta tack vare sin höga upplösning i tid och rum jämfört med andra radarer som används vid nederbördsmätning. En X-bandradar med en tidslig upplösning på en minut och rumslig uppRadar has been used since the 1940’s to measure and monitor precipitation. In recent years the X-band radar has emerged as a tool to improve the input data to rainfall-runoff modelling within Urban catchments thanks to its high spatial and temporal resolution compared to other radars used for precipitation measurements. An X-band radar with a temporal resolution of one minute and a spatial resolut

This study aims to rate the pollution risks of three fur farms breeding mink in Kristianstads municipality. The risk for each farm was analyzed according to the standardized method for polluted areas in Sweden (MIFO phase 1). The farms were divided into groups based on the risk that each farm has potentially polluted the soil, water or buildings that are located nearby or on the property. The stud

Scholars discuss about the importance of processes of communication in which all stakeholders actively participate influencing the constitution and development of change and organizations. However, communication professionals struggle to em-brace these assumptions and modify their roles and practices in these complex set-tings. This study aims to understand how practitioners adapt their roles in t

Detta examensarbete behandlar en energieffektivisering av Örebrogatan 2A-C i Kv. Hallonet som Helsingborgshem äger och förvaltar. Genom att ge förslag på olika åtgärder för att få en sänkt energianvändning på den idag energislukande byggnaden är förhoppningen att arbetet ska kunna användas som underlag i en framtida renovering av byggnaden.

By giving suggestions for different actions to get a reduced energy consumption on the today energy-wasteful building is the hope that the work and the conclusions can be used for a future renovation of the building. Whilst Sweden is growing with many new buildings, there a

I Peru påverkas beslutet att utbilda sig på eftergymnasial nivå, för både män och kvinnor, i hög grad av familjen. Särskilt på landsbygden är ojämlikheten hög, där kvinnor i mycket högre utsträckningen än män tenderar att inte vidareutbilda sig. Syftet med denna studie var därmed att undersöka hur föräldrastöd angående döttrars eftergymnasiala utbildning påverkas av tre variabler, baserade på sociIn Peru, the decision of pursuing higher education for boys and girls is dependent on one’s family. Especially in rural areas, the inequalities are high and girls are far less likely than boys to attend post-secondary education. Therefore, this study explored how parental support in relation to one’s daughter’s post-secondary education is influenced by three variables, based on the social cognitiv

The purpose of this thesis is to analyze the construction of a hearse made by Adiga on account for Nilsson Special Vehicles, NSV. The vehicle suffers from deformations in the rear as a result of mismatched gas springs and in side doors when these are kept open. Virtual models of side doors and rear are prepared in Catia and then analyzed in Ansys. For the tailgate, the minimum necessary force in
